Synopsis: Ridley Scott returns to the universe he created in Alien with Alien: Covenant, the second chapter in a prequel trilogy that began with Prometheus -- and connects directly to Scott's 1979 seminal work of science fiction. Bound for a remote planet on the far side of the galaxy, the crew of the colony ship Covenant discovers what they think is an uncharted paradise, but is actually a dark, dangerous world -- whose sole inhabitant is the "synthetic" David (Michael Fassbender), survivor of the doomed Prometheus expedition.
Alien Covenant to be released Oct. 6, 2017.
